How AI Search Is Recommending Revenue Cycle Management: Monthly Trends

Executive Summary

The Revenue Cycle Management (RCM) category experienced significant repositioning in September 2026, with athenahealth retaining the coverage lead at 38.7% but watching its gap to the next brand narrow sharply. R1 RCM rose to 30.4% coverage, now just 8.3 points behind the leader, while Waystar climbed to 24.5% and a newly tracked Optum entity entered at 24.3%, compressing the top of the category into a three-way contest for second place.

The strongest upward mover was R1 RCM, whose coverage rose 7.9 points from 22.5% in July to 30.4% in September, with rank-one recommendation share more than doubling from 6.8% to 14.1%. Optum entered the tracked set for the first time in September at 24.3% coverage with 91 of 375 valid recommendations, a significant arrival that coincided with the disappearance of the narrower Optum Workers' Comp And Auto No-fault tracking entity, which fell from 5.2% in both July and August to 0.0% in September.

The largest decline among continuously tracked brands was TruBridge, whose coverage fell from 3.8% in July to 1.1% in September, a significant 2.7-point drop that leaves the company with just 4 of 375 valid recommendations. athenahealth's position also eroded modestly across the three-month series, with raw mention presence falling from 89.2% in July to 78.7% in September, though its coverage decline of 3.1 points stayed within the benchmark's normal range.

Each monthly run begins with 779 prompt-surface observations (425 unique questions) in July, 785 (516 unique questions) in August, and 800 (579 unique questions) in September across the benchmark's defined AI/search surface universe. Of those, 779 in July, 785 in August, and 800 in September mentioned a tracked brand or competitor; 608 in July, 643 in August, and 504 in September were relevant, while 171 in July, 142 in August, and 296 in September were irrelevant. The public metrics use the 498 qualified observations in July, 462 in August, and 375 in September that survive both qualification stages. The benchmark tests six canonical AI surface families: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode.

Key Findings

Benchmark Context

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

The following metrics summarize category-level activity within the qualified benchmark set and provide context for the brand-level standings and movement data that follow.

Benchmark-Level Metrics

The intermediate August run saw valid recommendation shortlist share dip to 48.1% and recommendation-shaped answer share rise to 29.2%, before September settled between those levels. The larger story across the series is the rising share of answers carrying recommendation credit even as the qualified observation count declined.

AI Recommendation Trend

A new three-way contest for the top tier has formed behind the category leader

The RCM category shifted from a wide leader gap to a compressed top four in September. athenahealth remains in first place, but R1 RCM, Waystar, and the newly tracked Optum entity have closed the distance substantially, turning what was a stable hierarchy into a competitive top tier that warrants close inspection next month.

Four brands moved beyond normal month-to-month variation this month: R1 RCM, Waystar, Optum, and AGS Health all recorded significant gains, while TruBridge and the replaced Optum Workers' Comp And Auto No-fault entity posted significant declines. The category-level change came from the combination of these several substantial movements rather than a single driver.

What Changed This Month

R1 RCM: The largest riser, with rank-one recommendation share more than doubling

R1 RCM's valid recommendation coverage rose from 22.5% in July to 30.4% in September, a significant 7.9-point gain that moved the company from a distant second into a close challenger position. The company recorded 114 valid recommendations out of 375 qualified observations in September.

The move was driven by both wider presence and stronger placement. Raw mention presence rose from 33.3% in July to 49.6% in September, with the company present in 186 of 375 observations. Rank-one recommendation share more than doubled, from 6.8% to 14.1%, representing 53 rank-one recommendations in September. Top-three share rose from 16.9% to 21.9%.

The rank-one gain is the notable signal here: R1 RCM is not only appearing more often but is increasingly the first name AI systems put forward. This combination of presence growth and placement improvement suggests the brand is winning recommendation credit in new prompt contexts, not just appearing in more answers.

Highest-priority diagnostic: Which prompt patterns drove the rank-one gains, and against which competitors is R1 RCM now winning the first-position recommendation?

Waystar: Strong upward movement on both presence and placement

Waystar's valid recommendation coverage rose from 15.1% in July to 24.5% in September, a significant 9.4-point gain over the three-month series, with 92 of 375 valid recommendations in September. The largest single-month move was 6.3 points from August to September.

Raw mention presence climbed from 24.3% in July to 41.9% in September, reaching 157 of 375 observations and representing the largest presence increase in the benchmark's tracking. Top-three recommendation share rose from 8.2% to 12.8%, and rank-one share rose from 3.6% to 6.7%.

Waystar's growth is notable because presence, top-three placement, and rank-one credit all moved together, a pattern consistent with genuine recommendation gains rather than visibility alone.

Highest-priority diagnostic: Which surfaces and prompt topics are driving Waystar's simultaneous gains in presence and recommendation placement?

Optum: New entity enters tracking at substantial coverage

The September run introduced Optum as a tracked entity at 24.3% valid recommendation coverage, with 91 of 375 valid recommendations. The company was present in 178 of 375 observations, a 47.5% raw mention presence rate, and recorded 21 rank-one recommendations (5.6%).

This entry coincided with the removal of the narrower Optum Workers' Comp And Auto No-fault tracking entity, which had held 5.2% coverage in both July and August but recorded no qualifying observations in September. The benchmark's notable-gap analysis shows a 29.5-point separation between the two entities' coverage series, reflecting the change in how the Optum brand family is being measured.

The Optum entry at 24.3% coverage places the company effectively tied with Waystar for third and just 6.1 points behind R1 RCM, immediately reshaping the competitive picture at the top of the category.

Highest-priority diagnostic: Which prompt contexts and surfaces drive Optum's high presence and coverage, and how does its recommendation pattern differ from the narrower workers' comp entity it replaced?

athenahealth: Leader retains position while presence trails lower

athenahealth remains the category leader at 38.7% valid recommendation coverage in September, with 145 of 375 valid recommendations, but the company's raw mention presence has declined significantly from 89.2% in July to 78.7% in September, a 10.5-point drop. Coverage eased 3.1 points over the same period.

Rank-one recommendation share fell from 10.4% in July to 6.7% in September, a decline of 3.7 points, with 25 rank-one recommendations, while top-three share declined from 26.9% to 25.1%. Neither the coverage nor the top-three movement exceeded the benchmark's normal range.

athenahealth remains by far the most visible and most recommended brand in the category, but the sustained presence decline across two consecutive months narrows the buffer that once separated it from the chasing pack.

Highest-priority diagnostic: Which surfaces and prompt patterns account for the two-month presence decline, and are those the same contexts where R1 RCM and Waystar are gaining?

TruBridge: Coverage falls to the lowest level among actively tracked brands

TruBridge's valid recommendation coverage fell from 3.8% in July to 1.1% in September, a significant 2.7-point decline over the series, leaving the company with just 4 valid recommendations out of 375 qualified observations. The company recorded only 2 top-three placements and 1 rank-one recommendation in September.

Raw mention presence rose from 6.6% in July to 9.9% in September, reaching 37 observations, while net sentiment fell from 0.7 to 0.2. Top-three recommendation share dropped from 2.0% to 0.5%.

TruBridge is appearing in AI answers more often over the series while being recommended less and less, meaning its mentions are increasingly detached from recommendation contexts. With only 4 valid recommendations in September, small-count caution is essential when interpreting this movement.

Highest-priority diagnostic: In what non-recommendation contexts is TruBridge being mentioned, and which competitors are capturing the recommendation credit in prompts where TruBridge once appeared?

GeBBS Healthcare and AGS Health: Mid-tier risers building on wider presence

GeBBS Healthcare's coverage rose from 8.0% in July to 13.9% in September, a significant 5.9-point gain with 52 of 375 valid recommendations, moving the company to 5th place. Raw mention presence nearly doubled from 9.4% to 21.3%, reaching 80 observations, though top-three share rose only modestly from 3.2% to 4.0%.

AGS Health's coverage rose from 4.8% in July to 8.8% in September, a significant 4.0-point gain with 33 of 375 valid recommendations, and its 6th-place rank. Raw mention presence climbed from 6.4% to 13.1%, while top-three share moved from 1.4% to 2.4%.

Both mid-tier brands built their gains primarily through wider presence rather than stronger placement within answers, a pattern that can be more fragile than top-of-list wins.

Highest-priority diagnostic: For each brand, which question topics expanded, and are those new mentions converting into recommendation credit or remaining as secondary presence?

Buyer-Intent Interpretation

Every qualified observation in July, August, and September fell into the brand recommendation cluster, with 498 observations in July, 462 in August, and 375 in September assigned there. No observations were recorded in the pricing and value or multi-brand comparison clusters in any of the three months.

This concentration means the public benchmark can confirm which vendors AI systems recommend for RCM and with what frequency, but it cannot yet answer questions about how AI systems characterize pricing differences between vendors, how they compare value propositions, or where each brand ranks in head-to-head scenarios. The commercial weight of recommendation coverage is clear, but the reasoning underneath those recommendations remains outside the reach of the current public benchmark set.

Brand Opportunity Summary

The benchmark identifies where attention is warranted across the RCM category; a company-level analysis is needed to explain why these patterns are emerging for any individual brand.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations capturing the query, the AI surface, the recommendation outcome, the rank position, sentiment, and citations where exposed. Company-level analysis can go deeper into prompt phrasing, competitor presence, surface-level differences, and the evidence sources that shape each AI answer. Source presence in an AI output is not automatically treated as proof of causation.

Report-Specific Interpretation Notes

• The qualified benchmark denominator (375 observations in September) differs from the raw collection size (800 prompts), and brand-level percentages reflect only qualified observations.
• Small-count movements, such as TruBridge's decline to 4 valid recommendations, warrant caution in interpretation; a change of a few observations can move the percentage meaningfully.
• Movement between months identifies changes worth investigating; it does not by itself establish the cause of those changes. The Optum tracking change, in particular, reflects a shift in how the brand family is measured rather than a purely organic coverage movement.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

The aggregate percentages in this report raise questions that the public benchmark cannot answer: Which high-intent prompts is each vendor winning or losing? When a brand loses the recommendation, which competitor takes it? What attributes and capabilities do AI systems associate with each RCM vendor? Which external sources, reviews, and publications are shaping those answers? These are the questions beneath the numbers, and they determine whether a coverage figure represents durable authority or a fragile mention.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It identifies where a brand is genuinely recommended versus merely visible, which competitor is capturing the credit it loses, and what evidence gaps are holding back stronger recommendation placement.
